[Solved] Remote screen wake-up of NSPanel with Tasmota using MQTT - how to do it?

Is it possible to remotely wake up an NSPanel screen with Tasmota using MQTT - if so, how to do it?

Yes, remotely wake up an NSPanel screen with Tasmota using MQTT is possible. MQTT is a communication protocol designed for use in IoT devices. It allows us to remotely control various elements of devices, including waking up the screen.

First make sure your NSPanel screen is properly configured with Tasmota and connected to a Wi-Fi network. You should see the MQTT configuration menu in Tasmota - if you don't see it, make sure you have the latest version of the software.

Here are the steps you need to take to configure MQTT and remote screen wake-up:

1. Configure MQTT in Tasmota. In the MQTT configuration menu in Tasmota, enter the MQTT server address (broker), username and password (if required), and the topic name (Topic) for your device. The Topic name is a unique identifier that will allow you to communicate with your device using MQTT.

2. Install and configure the MQTT client on the device from which you want to control the screen. This could be a computer, laptop or smartphone, for example.

3. To remotely wake up the screen, you need to send the appropriate command to Tasmota using MQTT. This command could look like this: `cmnd/[subject name]/POWER ON`. Instead of `[subject name]`, type the subject name you have set up in Tasmota.

4. Send the command to Tasmota using the MQTT client. If everything has been configured correctly, the screen should wake up.

Remember that MQTT communication is invisible to the human eye, so the only evidence of whether everything is working correctly will be the screen response. If the screen does not wake up, check the MQTT settings in Tasmot and in the MQTT client.

Hope this information was helpful. If you have any questions or encounter problems, please let me know!

You need to concentrate more. I have everything configured correctly. I can send and receive mqtt in any topic. The suggestion given is incorrect.

Sorry for the confusion. If your Tasmota and MQTT system is already configured and working correctly, then waking up the NSPanel screen is feasible.

The first step is to understand that Tasmota uses MQTT topics for communication. Depending on how you have configured Tasmota, the wake-up topic will look roughly like this: `cmnd/your_device/POWER` (where "your_device" is the name you have given your device in Tasmota).

To wake up the screen, you must send the "ON" command to this subject. You can do this using any MQTT client.

For example, if you are using mosquitto (a popular MQTT client), you can run the following command in a terminal (assuming mosquitto is installed on the same computer as the MQTT broker is running on):




After sending this command, the NSPanel screen should wake up.

Hope this information is helpful. If you need any more help, please let me know!

I am sorry for the mistake. As for remote control of the NSPanel screen via the MQTT protocol in Tasmota, the subject matter is a bit more complex and requires specific configuration.

Unfortunately, Tasmota does not have direct support for controlling the NSPanel screen wake-up directly via MQTT. However, it is possible to control some NSPanel screen features, such as brightness or background colour, if they are available as default features on a specific NSPanel model.

Most NSPanels allow screen wake-up via motion detection, but this feature is only available locally on the device and is not supported by MQTT.

However, there are several workarounds - one is to use a script on the Tasmota-enabled device that wakes up the NSPanel screen when it receives a specific MQTT signal. Such a script could use features available in Tasmota to control GPIOs that are accessible via MQTT.

Alternatively, if your NSPanel device is compatible with Home Assistant, you could set up an automation in Home Assistant that wakes up the NSPanel screen when it receives a specific MQTT signal.

Please note that everything depends on the specific NSPanel model you have, so I cannot guarantee that the above solutions will work for you. Make sure you know the capabilities of your device and always be careful when tampering with system settings.

From what I gather SonOff NSPanel comes in NSPanel and NSPanel Pro versions. I have the former. What you write are some generalities. I need specifics. Is it possible or not on this model. If so how.


how would this configuration look like?

I am sorry for the confusion. I apologise for the confusion.

If you have the SonOff NSPanel, it should support MQTT and be compatible with Tasmota, but controlling the screen directly via MQTT can be a bit tricky.

Have you tried using the "DisplayWake" command? This is the command that should wake up the NSPanel screen. Below is an example of the command that you can execute from the Tasmota console on your device:




Assuming "your_device" is the name of your device in Tasmota.

If the "DisplayWake" command does not work, it probably means that Tasmota on your NSPanel does not support direct screen control. If this is the case, the only solution would be to use the wake-up function when motion is detected on the NSPanel device, if available.

Alternatively, you can try complex configuration using scripts and GPIOs, but this can be difficult and risky without the right knowledge and experience.

I am here to help, but some things may be beyond my reach, and controlling the NSPanel screen via MQTT may be one of them. Please feel free to ask for your understanding.
